REED AN D COIN-CONTROLLED CALENDAR.

Application filed December 16, 1921. Serial No. 522,772.

1 *0 aZZ whom it may concern:

Be it known that I, GEORGE M. DIEHL, a citizen or the United States, residing at Wabash, in the county of Wabash and State oi Indiana, have invented a new and useful Coin-Controlled Calendar, of which the following is a specification.

The object of my invention is to make a coin depository comprising con-controlled calendar mechanism,the arrangement being such that by the insertion of a coin and the manipulation 01 an operating lever the cal endar mechanism may be advanced step by step to indicate the date and also to indicate the minimum number of coins deposited in the repository in relation to the calendar period. p

The accompanying drawings illustrate my invention. Fig. 1 is a fragmentary elevation in partial vertical section showing the coinreceiving mechanism and the operating lever; Fig. 2 a fragmentary elevation of the ratchet and pawl mechanism in initial position; Fig. 3 a view similar to Fig. 2 with In the drawings, 20 indicates a suitable enclosing casing having a primary coinreceiving slot 21 and associated guide 22; a supplemental coin-receiving slot 23 and associated guide 24; and a removable coin receptacle 2 5.

Alined with the lower end of guide 22 is a coinreceiver 26 provided at its lower end with a finger 27 upon which the coin will primarily rest so long as it is retained in that position by swinging retaining finger 28 which is carried by shaft 29 'ournaled in a suitabl frame 30. Opposing nger 28 is a finger 31 normally spaced from finger 28 by at least the thickness or the coin. The finger 28 is slotted, in alinement with finger 31 and 28.

31, so that, in the absence of a coin, finger 31 can have no effect upon finger 28.

- Finger 31 is part of a plate 32 which is slidably supported in slots 33 and 34 in,

frame 30 and may be reciprocated by means of a lever 35 which is projected through the casing 20.

- When a coin is deposited in slot 21 it drops upon shell 27 and lies between the fingers Manipulation of lever 35 will then swing fin 'er 28 and cause movement of two pawls 36 and 37 whichare carried by arms 36 and 37 respectively, secured 'to shaft 29. These pawls, acting respectively upon the 14-tooth ratchet wheel 38 and the 31-tooth ratchet wheel 39 cause a one step advancement of the week-day dial'40 and the number dial 41 so as to' bring appropriate portions oi th -faces of said-dials opposite the sight opening 42 of the casing. The number dial 41 is provided-with a circular series of numbers from 1 to 31 and the weekday dial is'provided with two sets of weekday designations. I provide dial- 40 with two sets of week-day designations merely because it is more convenient to 'form a '14- tooth ratchet wheel than a 7-tooth andpermits a shorter operating stroke. Pawl 36 is so formed as to be incapable of driving ratchet wheel 38 more than one step, the pawl being curved, as clearly indicated in Fig; 3, adjacent its active end, and consequently this pawl rides out ofengagement with the ratchet wheel 38 during'the final portion or the stroke of the pawl. The total possible movement of rock shaft 29 is enough to advance the ratchet wheel 39 through four steps but such movement is normally restricted to a single step by means of a fingrcr 37" carried by arm 37', and a shoulder 43 carried by an arm 44 hung upon pin 45 of frame 30 by means of a downwardly open slot 46 which permits ready removal without dismantling the structure as a whole. The finger 37" is slotted to receive, guide and support the end of arm 44.

Assuming that the apparatus has been properly set and started on the first ofJannary, the 30th step of advancement of ratchet wheel 39 will bring a finger 47, which'is formed integrally with the ratchet wheel into engagement with a projection 48 on the lower edge of arm 44 and thus raise shoulder 43 so that pawl 37 might be adi I i I 1,471,836

'vanced more than one step but, as January with has its drop-off brought into position to permit an arm .52, which rests on the periphery of the cam to drop and, though i the medium of a finger 53, which is projected through a swinging arm 54, to permit spring '55 to draw arm 54 downwardly and cause the gravity pawl 56 carried by the arm, to act upon a ratchet wheel 57 and advance it one step. This ratchet wheel57 is integral with disk and is carried by a sleeve 58 journaled on the shaft 38, which connects ratchet wheel 38 and dial 40. The sleeve 58 serves as a bearing for the element 394751. The advancement of ratchet wheel 57 brings a February notch of disk 50 into alinement with the path ofmovement of finger 49. Element 50 is divided into twenty-four equal angular spaces and ratchet wheel 57 is a 24-tooth ratchet. A disk 50 is carried by sleeve 58 and carries month designations visible through the sight opening 42.

Advancement of element 50 just referred to brings=-a pawl 60, which is pivotally mounted on the element 50, so that its free end lies beneath a finger 61 carried by the arm 44 and on the actuation which corresponds with the 27th day of February a pin 62 (Fig. 5) carried by the ratchetwheel 39, engages said pawl and causes it to lift arm 44 so as to retract shoulder 43 from blocking position so that, on the actuation corresponding with the 28th of February, the finger 49 will enter the'long February slot of element 50 and permit a swing of the actuating member 35. which will be sufiicientto cause pawl 37 to move ratchet 39 through four spaces. This movement will, of course,

move cam 51 enough to cause an actuation of ratchet wheel 57 by pawl 56, in the man- ]ner already described, as soon as finger 49 is retracted from the February slot of element 50.

At each angular portion of the element 50 which will lie opposite finger 49 on the last day of athirty day month, the periphery of element 50 is provided with a shallow notch, as indicated in Fig. 6 at the Reversemovementof the ratchets 38and 57 are prevented by spring urged pawls and 71 respectively and these pawls are conveniently pivotally supported on a cross bar 72 of the frame by an open ended slot in the arm as indicated at 73 (Fig. 2) in order to facilitate disassembly-of the parts without taking the frame apart. This type of construction is utilized in many places, as for instance arm 37 (Fig. 4) is forked upon shaft 29 by the open slot or fork construction as indicated at 75, and arm 36 (Fig. 3) is similarlyv forked on shaft 29 as indicated at 76. r r

The gravity, pawl 56 is provided with a tail 56 which, when the pawl is moved in the actuating direction and has reached the end of its stroke, comes into such relation with the ratchet wheel, vas indicated in dotted lines in Fig.2, as to prevent overthrow of the ratchet wheel. The pawl is provided to prevent reverse movement 5- of ratchet wheel 39.
